To aZZ whom it may concern:

Be it known that I, AUoUsTUs l/VILLIAM.

Lotus ScHnnMULY, a subjectof the King of Great Britain, residing at 'Stonecroft, Stone Cot Hill, Sutton, in the county of -Surrey,

England, haveinvented new and usefullm provements in Devices for suspending and Releasing Ships Boats (for which I have filed application in Great Britainonthe 24th day ofJuly,1918, Patent No-12,077,)

of which the following is aspecification. My invention relates to devices forsuspending and releasing shlps boats and .for

' :malogous purposes, the said devicesbeing of the kind in which the boat is suspended by the falls or suspending tackle (the lower ends of which are restrained from 'outward movement, relatively to each other, by: a tie-rope) engagingrwith hooks at, or'to-a.

wards, the respective ends of the boat, one,

or both, of these hooks being released fromengagement wlth the falls, or suspend ingtackle, to liberate the boat after lower-..

ing. In devices of the aforesaid kind the hooks are maintained in their engagingposition'by pins, catches, or their equivalent, which pins, or catches," or the1r equivalent,

are withdrawn, or-otherwise manipulated, when it is required to liberate the boat. My invention has for its object to' provide improved devices of the afores,aid ;-kind which are very simple 1n constructlon and very readily operated for attachment and dewhich the pins, catches, or their equivalent, hitherto proposed for maintaining the hooks in engagement withthe falls, ing tackle, are dispensed with.

I will presume, for the purposes of description only, that the devices according ,to

. my invention are to beemployed :Eorxsus pending ships boats from their fldavits.

According to my invention the boat to be suspended is provided, towards both its bows and stern, with a hook, one or each of such hooks being a lever-hook capable of turning upon a centre and retained in ,securing position by the strain exerted on one side of the said centre by connected suspending devices which engage the said books, the said levenhook, or each of such lever-hooks, being provided with means by which the hook can be turned into such position that the suspending device connected or suspend,

-with it comes towards the other side of the said centre andthe strain then eXerted'b'y the said connectedr suspended devices will bring 'the lever-hook into the position in my invention can be constructed and applied, as boat-suspending and releaslng gear,

but I do not limit myself to the precise de-' tails of these constructions. 7

Figure l is a longitudinal section of a boat showing an arrangement wherein a leverhook is used at one end of the boat. v Figure 2 is alike View of an arrangement wherein a lever-hook is used each end of the boat. v 1 i Referring first to Figure 1. a v The part ofthe boat towards the fore-end is provided with a fixed book A, somewhat inclined in an upwarddirection towaigds the bows, and the part of the boat towards its after end is provided with'side-pieces, (one 01 which is seen at B) constituting a double standard between which is the lever-hook C,

' capable of turning upon a centre-pin? carried, by the said double standard,above the, position which the hook c of the said lever O takes when it is inyits suspending and securing position so that the link of thesuspending tackle, when inthatposition, has

the part which takes the strain of the suspending tackle to one side off the centre 1 upon which the lever-hook turns. The sus pending tackle (the lower ends of which are seen at D) can he carried, in any usual, or suit-able way, from thewdavits so that the links (Z of, the lower blocks (l ofthe tackle will respectively engage the hooks A and c. -'Il he said blocks, or ,the links carried thereby, or other suitable parts of the'tackle engaging the respective hooks, (for ex ample, as illustrated, the rings (Z connecting the blocks and links) are connected by any suitable tie-rope, or the like, such as that shown at E, which will ensure the proper engagement of the respective hooks and links when in the suspending position illustrated, the strain of the tie-rope E, or the like, tending, by its connecting the ends of the falls, or suspending tackles, together to keep the after-link d on the inner side of Price,

the centre'uponwhich the lever-hook 0 turns the boat.

To attach the boat for suspension, the link 03 of the-forward block is passed under the fixed hook A- The lever-hook C towards the after-end of the boat is turned upwards upon its centre-pin b, and engaged. with the link d of the other block. Then the lever-hook C is turned down-between theside-pieces B of the aforesaid standard until the link d of the after-block has passed the centre upon which the hook turns, that is, to the position illustrated. Torelease the boat the tail'oif the lever-hook is pulled tow'ards the stern of the boat until the link d of the afterblock is moved to the otheri side, of the centre upon which the hook turns whereupon V the strain of the suspending tackle will,

' the-fore-link will slip from the inclined fiired hook A at-the bowsand the boat will be at ".falls, or suspending tackles, both when enthrough the link 0Z of the after block, in-

I stantly turn the lever-hook'C into such a position that the book 0 will slip from the link 03 at the stern end of the boat, whilst once released.

The lever-hook C'may be provided with any suitable means for operating it for release, such as the short rope to hepulled,

and the standard between the side pieces of which the lever-hook is carried, may be shaped so that, whenthe lever-hook is in its engaging,'or suspending, position, as shown in the drawing, the link d of the suspending,

"tending between said suspending elements I and serving to'hold the latter in suspending tackle will be practically enclosed between the hook c and the adjacent partsof the said standard 13. V The hook A, and the standard B, are shown as being connected to the boat by hinge-joints, at a and 6 respectively; but they can be" connected in any other con venient way.

The tie-rope, .or the like, connects the two gaged with the hooks and when released therefrom which not only keeps the hooks securely engaged with the links when the of said hook to and boat is suspended, butv on release at once clears the occupants of the boat of everyunder control.

Although I have mentioned the lever-hook as beingemployed at one end only, such an arrangementmay, if desired, be used at both ends in which case the boat may be released from eitherend.

1 Figure 2 shows a modification in which lever-hooks are thus employed at each end of the boat. The parts at both, ends are marked with letters oi. reference the same as those used to denote like parts of the lever-hook and connections shown at the stern of the boat in Figure 1 and-require no further description.

. What I claim is LA suspending and releasing device comprising'twolsupports. at least one of which has a piv tedlever hook, suspensionelements engaglng said supports, means for moving said pivoted lever hook to shift the hook engaging suspension element across the axis displace the strain of suspension from one to'the other side thereof, tie-means connecting said suspension elements, and serving, under the strain of suspension, to urge the hook open orclosed substantially as described.

2. A suspending and releasing device having two supports, at least one of which comprises a hook having apivoted member,'suspending-elements adapted to engages-aid supports, that which engages the hook ly-' ing in suspending 'position'to one side of the axls" of the plvoted member, tie-means exposition, together with means to swing the pivoted member onits axis to free the suspending element from the hook engaged thereby.
